Abstract: A computer-implemented method and system for associating one or more wireless tags with one or more products is disclosed. The method comprises communicating wirelessly with the wireless tag(s) using a mobile device, associating the wireless tag(s) with a user account, and assigning at least one of the wireless tag(s) to a current product or a new product. The system comprises one or more wireless tags, a mobile device configured to communicate wirelessly with the wireless tag(s), and a storage server or cloud computer configured to (i) send, receive and store the information regarding the wireless tag(s) and the associated product and (ii) store and execute an analytics program or web application configured to track the information regarding the wireless tag(s). A computer-readable storage medium enabling the method on the mobile device and a system for managing one or more wireless tags associated with one or more products are also disclosed.

Abstract: A matrix connection device disposed between n unidirectional energy sources (PV1, PV2, PVn) and n power converters (C1, C2, Cn) for the purpose of powering a common load (10), said device comprising: n matrix switch units (I1, I2 to In), each of which comprises n link switches (Ki1, Ki2 to Kin) having their outlets connected together and having their n inlets connected to the n outlets of said photovoltaic panels and/or wind turbines; at least one additional switch unit (In+1) comprising n switches (Kn+11, Kn+12 to Kn+1n) having their outlets connected together and their n inlets connected to respective ones of the n outlets of the unidirectional energy sources; and a monitoring and control circuit (14) for starting up or not starting up said power converters as a function of the power available at each of said unidirectional energy sources, and then for keeping them switched on or for deactivating them as a function of the power consumed by each of them.

Abstract: On a printed circuit or substrate board (10) designed to receive electronic components and having conductive tracks (12) printed on said board, one or more conductive bars (18) are provided that are mounted one after another between conductive link surfaces (140, 142, 144), the conductive bars (18) being electrically interconnected during a subsequent soldering process that is either a wave soldering process or a soldering process in a reflow oven.

Abstract: A power converter having two main switches connecting an outlet either to a positive rail or to a negative rail, two free-wheel diodes enabling the current through the load to be maintained, two snubber capacitors, and an auxiliary circuit. The auxiliary circuit includes an auxiliary inductor in series with two auxiliary switches coupled between the outlet and a midpoint of a capacitive voltage divider that provides a midpoint voltage. A detector detects current oscillation between the auxiliary inductor and the snubber capacitors, and then switches off the oscillation current and allows the intended main switch to conduct in response to the interruption.

Abstract: A power converter comprises two main switches connecting an output either to the positive rail or to the negative rail. Two freewheel diodes for maintaining the current in the load, two snubbers and an auxiliary circuit including an auxiliary inductor in series with two auxiliary switches connected between the output and a mid-point of a capacitive voltage divider supplying a median voltage. Any error of the median voltage relative to its nominal value is evaluated and the main switches are additionally commanded, depending on the direction of the error, for a time period dependent on the amplitude of the error, in order to cause an additional current in the auxiliary circuit to correct the error at least in part.
